# FrostFS S3 Gateway FrostFS S3 gateway provides API compatible with Amazon S3 cloud storage service. ## Installation ```go get -u github.com/TrueCloudLab/frostfs-s3-gw``` Or you can call `make` to build it from the cloned repository (the binary will end up in `bin/frostfs-s3-gw` with authmate helper in `bin/frostfs-s3-authmate`). To build binaries in clean docker environment, call `make docker/all`. Other notable make targets: ``` dep Check and ensure dependencies image Build clean docker image dirty-image Build dirty docker image with host-built binaries format Run all code formatters lint Run linters version Show current version ``` Or you can also use a [Docker image](https://hub.docker.com/r/nspccdev/frostfs-s3-gw) provided for released (and occasionally unreleased) versions of gateway (`:latest` points to the latest stable release). ## Execution Minimalistic S3 gateway setup needs: * FrostFS node(s) address (S3 gateway itself is not a FrostFS node) Passed via `-p` parameter or via `S3_GW_PEERS__ADDRESS` and `S3_GW_PEERS__WEIGHT` environment variables (gateway supports multiple FrostFS nodes with weighted load balancing). * a wallet used to fetch key and communicate with FrostFS nodes Passed via `--wallet` parameter or `S3_GW_WALLET_PATH` environment variable. These two commands are functionally equivalent, they run the gate with one backend node, some keys and otherwise default settings: ``` $ frostfs-s3-gw -p 192.168.130.72:8080 --wallet wallet.json $ S3_GW_PEERS_0_ADDRESS=192.168.130.72:8080 \ S3_GW_WALLET=wallet.json \ frostfs-s3-gw ``` It's also possible to specify uri scheme (grpc or grpcs) when using `-p` or environment variables: ``` $ frostfs-s3-gw -p grpc://192.168.130.72:8080 --wallet wallet.json $ S3_GW_PEERS_0_ADDRESS=grpcs://192.168.130.72:8080 \ S3_GW_WALLET=wallet.json \ frostfs-s3-gw ``` ## Domains By default, s3-gw enable only `path-style access`. To be able to use both: `virtual-hosted-style` and `path-style` access you must configure `listen_domains`: ```shell $ frostfs-s3-gw -p 192.168.130.72:8080 --wallet wallet.json --listen_domains your.first.domain --listen_domains your.second.domain ``` So now you can use (e.g. `HeadBucket`. Make sure DNS is properly configured): ```shell $ curl --head http://bucket-name.your.first.domain:8080 HTTP/1.1 200 OK ... ``` or ```shell $ curl --head http://your.second.domain:8080/bucket-name HTTP/1.1 200 OK ... ``` Also, you can configure domains using `.env` variables or `yaml` file. ## Documentation - [Configuration](./docs/configuration.md) - [FrostFS S3 AuthMate](./docs/authmate.md) - [FrostFS Tree service](./docs/tree_service.md) - [AWS CLI basic usage](./docs/aws_cli.md) - [AWS S3 API compatibility](./docs/aws_s3_compat.md) - [AWS S3 Compatibility test results](./docs/s3_test_results.md) ## Credits Please see [CREDITS](CREDITS.md) for details.
